Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

Chevy Express, GMC Savanna reportedly ending production for 2025

The oldest commercial vans on the market may only have a few years left, according to a report from Autoweek. The news outlet cited a "competitive analysis source" in saying that the Chevy Express and GMC Savanna commercial vans would be discontinued after the 2025 model year. They would then be replaced by a new electric van, likely Ultium-platform based, for the 2026 model year. We reached out to GM for comment, and this is the official statement sent to us: "We have said in the past that as part of GM’s larger EV acceleration plans that we will add two new vehicles to our commercial portfolio. The first is a full-sized battery electric cargo van and the second is a medium-duty truck that will put both Ultium and our Hydrotec hydrogen fuel cell technology to work. We have not disclosed timing, names or shared any other details, so any articles reporting more are purely speculative." The GM vans are mighty old, having been introduced for the 1996 model year. They've barely changed since then, having received just some facelifts and updated powertrains over the years. And with GM's electrification plans, we're not surprised that these vans will be on the way out. We do have some disagreement about the reported timeline for replacement, though. We suspect that the upcoming electric vans will overlap with the old vans for at least a year. The reason being that there are a lot of these vans on the road, and there are a lot of pieces of equipment that fit them. Box vans, buses and more have components that have been designed for the Express and Savanna. If you're a fleet that has invested in these components, you might not be ready to shift over to a whole new platform. So GM will probably want to give fleet buyers one last opportunity to replace any old vans before committing entirely to a new electric van platform. It will also be interesting to see what kind of market the GM electric vans enter. Ford already has its electric Transit on the way, and Stellantis will be launching the Ram ProMaster electric van next year. Those are both based on existing gas-powered vans. And GM itself has already delivered the first of its larger BrightDrop EV600 electric vans to FedEx. The coming GM vans will likely be new platforms, which could give them performance and range advantages, though the Ford and Stellantis vans will have the advantage of being compatible with equipment for the gas variants.

Chevy Corvette is latest car breached by hackers

UPDATE: This story has been updated with comment from General Motors. In the latest car-hacking exploit in a summer full of them, researchers from the University of California-San Diego say they've found a way to manipulate braking in a 2013 Chevrolet Corvette. The vulnerabilities may not be limited to that model. Cyber-security researchers breached the car's security systems via a device they had plugged into the Corvette's OBD-II port, and through that connection, they sent messages that could turn windshield wipers on and off and tamper with the brakes as the car drove at low speeds. It's the latest in a series of car hacks that involve access to critical systems obtained via the OBD-II port, where drivers can plug in devices that provide anything from diagnostic information for mechanics to driving information for insurance companies. Last November, cyber-security engineers from Argus Cyber Security remotely controlled vehicle functions in a car that had a OBD-II dongle called a Zubie installed. In January, researchers from Digital Bond Labs found security holes in an information-tracking dongle popular with more than 2 million Progressive Insurance customers. Those came before prominent hacks unveiled in recent weeks, in which researchers remotely commandeered control of a Jeep Cherokee and, separately, showcased problems with GM's OnStar infotainment system. Regarding the dongles that plug into the OBD-II ports, Stefan Savage, a Cal-San Diego professor involved in the research, tells WIRED that, "we acquired some of these things, reverse-engineered them, and along the way, found that they had a whole bunch of security deficiencies." Savage and others unveiled the latest study at the Usenix security conference Tuesday. In a video of their exploit entitled "Fast and Vulnerable," they show how they sent SMS messages from a smartphone to the dongle plugged into the car's OBD-II port. From there, their messages accessed the CAN bus, a network on the car that connects individual electronic control units, which control dozens of vehicle functions. As they send the commands to brake the car, the driver of the Corvette notes "the pedal doesn't react to any pressure." General Motors issued a written response Wednesday, warning drivers to be careful with third-party devices they plug into their OBD-II ports.
